Exosomes are small (~30-150 nanometers) vesicular bodies secreted by cells. Exosomes play important roles in cellular communication through the cargo they carry from donor cell to recipient cell. This cargo can include nucleic acids such as mRNA and miRNA, protein folding chaperones, and biologically active enzymes. Ongoing research is focusing on using exosomes as potential biomarkers, as their composition is known to undergo changes during times of stress.
The annual symposium on Viral Oncology and AIDS Malignancy will take place at Duke University on December 3rd. Planned speakers include SJ Gao, PhD U. of southern California, P Lamber, PhD U. of Wisconsin-Madison, Nancy Raab-Traub, PhD U. of North Carolina-Chapel Hill.

28 death have been attributed to West Nile Virus infections in 2015 in California (as of Nov. 1st). This epidemic is on par with 2014's 31 death from West Nile Virus in California.
West Nile Virus is a single-stranded RNA virus of the Flavivirus genus in the Flaviviridae, which also includes Dengue Fever and Yellow fever. No vaccine is currently available for the West Nile Virus. The Dittmer lab continues active research on the pathogenesis of the West Nile Virus.
The Virus is spread through mosquitoes bites. It is found in North-America, Africa, Oceania and West, South and Central Europe. Experts have suggested the recent outbreak in California is due to the drought, causing mosquitoes to move to higher densities of population.
On October 1st, Dr. Ted Trimble was hosted by the Lineberger Comprehensive Cancer Center and the Gillings Global Gateway at the Gillings School of Public Health. During his visit, he met faculty and students, discussed global cancer research from the perspective of the NCI, and attended a poster session on topics relating to various aspects of current global cancer research. Dr. Trimble highlighted the need for collaboration of US cancer centers with low and middle-income countries, in particular for the purpose of developing affordable approaches to cancer treatment.

UNC Lineberger reports on the collaboration of George Liomba, a Malawian Pathologist, and UNC Lineberger Global Oncology program. Their partnership has help build a pathology lab accelerating the turnaround time of test results. Members of UNC Lineberger have the opportunity to study diseases much more common in southern Africa than in North America, such as virus-linked Lymphomas and Kaposi's Sarcoma.
